The Neotropical genus Teramocerus Schoenherr, 1840 is redefined on the basis of a taxonomic revision and of a phylogeny. In addition to several other characters of the external morphology, detailed examination of sclerites and ornamentation of the internal sac of aedeagus was used for the first time in Brentidae Billberg, 1820, providing several new characters, with also potential interest for the study of the tribe Acratini and possibly the family. Two new synonymies are proposed at generic level: Acratus Lacordaire, 1865, n. syn. for Teramocerus and Proteramocerus Kleine, 1921, n. syn. for Teramocerus. Five new species are described from Amazonian Basin and French Guiana: Teramocerus amazonicus n. sp., T. brulei n. sp., T. curtirostris n. sp., T. pulchriformis n. sp. and T. trichosternon n. sp. Because of the synonymy between Proteramocerus and Acratus with Teramocerus, seven new combinations are proposed: Teramocerus appendiculatus (Soares & Scivittaro, 1972) n. comb., T. badius Boheman, 1840, comb. rev., T. forficula (Soares & Scivittaro, 1972) n. comb., T. opacus (Perty, 1832) n. comb., T. pulcher (Soares & Dias, 1971) n. comb., T. suturalis (Lund, 1800) n. comb., and T. zellibori (Soares & Dias, 1971) n. comb. Several new synonymies are given at specific level: Acratus fidelis Kleine, 1927, n. syn. for Teramocerus badius, Proteramocerus aeneus Soares & Dias, 1971, n. syn for T. eletus Kleine, 1927, P. oliveirai Soares & Dias, 1971, n. syn. for T. eletus Kleine, 1927, P. emendatus Kleine, 1927, n. syn. for T. janthinus Boheman, 1840, P. eminens Kleine, 1927, n. syn. for T. janthinus, P. villens Soares & Dias, 1971, n. syn. for T. janthinus, Brenthus acutipennis Boheman, 1833, n. syn. for T. opacus, T. obscurus Perroud, 1853, n. syn. for T. opacus. Trachelizus helmenreichii Redtenbacher, 1868 is removed from synonymy with Teramocerus suturalis and transferred to the genus Nemobrenthus Sharp, 1895, giving the new combination Nemobrenthus helmenreichii (Redtenbacher, 1868) n. comb. Maps are provided for examined specimens of each species. An identification key is given for males and females. In a second part, a phylogenetic analysis is made to test monophyly and species assemblage of the newly defined genus Teramocerus. Maximum parsimony and Bayesian analysis were performed on a matrix of 40 morphological characters of the adults and 25 taxa; 19 were supposed to belong to Teramocerus in the meaning given here, the six others to various Acratini and Trachelizini. Both analyses show that type species of all the genera synonymized are indeed completely included in Teramocerus, this genus being then monophyletic in its new definition.

The taxonomy of two poorly known species of rhizopine crabs, Ceratoplax truncatifrons Rathbun, 1914, and C. fulgida Rathbun, 1914 (Brachyura Linnaeus, 1758: Pilumnidae Samouelle, 1819) is clarified on the basis of the type material from the Philippines. A new species, C. margarita n. sp., is described from Papua New Guinea. It can be distinguished from the above two species (and all congeners) by its carapace, sternal and gonopod characters.

Among Afrotropical representatives of the genus Chimarra Stephens, 1829 (Trichoptera: Philopotamidae), the minima group is defined to include a number of closely related species that lack the mesal lobe of tergum X, have a membranous tergum IX, and also have characteristic structures of the inferior appendages and phallic apparatus. A preliminary list of the species is proposed. The descriptions of Chimarra ambaja Mosely, 1939, Chimarra callasae Gibon, 1982, Chimarra sassandrae Gibon, 1982 and Chimarra toubaensis Gibon, 1985 are supplemented. One synonymy is established Chimarra petri Gibbs, 1973 as a junior synonym of Chimarra minima Ulmer, 1907. Five new species are described: Chimarra loffae n. sp. from Guinea, Chimarra sanagae n. sp. and Chimarra assambae n. sp. from Cameroon, Chimarra vulgaris n. sp. and Chimarra antsymeloka n. sp. from Madagascar. New citations for West Africa, Cameroon and Madagascar, new distribution and ecological data are included and analysed.

Ce travail est un récapitulatif de nos connaissances sur les diverses espèces de collemboles littoraux interstitiels terrestres de la côte Est de Madagascar. Il est complété par l'étude pendant deux ans des répartitions horizontale et verticale du peuplement de collemboles de la plage d'Antalaha sur cette côte.

A new species of the family Paguridae Latreille, 1802, Michelopagurus tangaloa n. sp., is described from deep waters (485–1145 m) off the coast of Moorea, French Polynesia, South Pacific. This new species is the fifth known in the genus Michelopagurus McLaughlin, 1997, and the third from the Indo-West Pacific; the other two species are distributed in the Atlantic Ocean. All five species are rarely collected and most are known from a few type specimens. The new species most closely resembles its Indonesian congener M. chacei McLaughlin, 1997 but can be differentiated by having an acutely triangular rostrum terminating in a small spine, instead of the broadly rounded, terminally unarmed rostrum in M. chacei. Other subtle differences are: corneas reduced, not dilated or wider than distal width of peduncle in M. tangaloa n. sp., whereas corneas are weakly dilated and wider than distal width of peduncle in M. chacei; right cheliped dorsal surface of palm lacking spines, and carpi at most with weak dorsomesial distal row of small blunt spines in M. tangaloa n. sp., whereas the dorsal surface of the palm has a row of distinct spines, and carpus with dorsolateral and dorsomesial rows of distinct spines in M. chacei. A key to assist in the identification of all species of the genus is provided.

This paper describes Peripodisma llofizii n. sp., discovered during the summer of 2014 on Mount Llofiz around 1700 m above sea level, located in the North of Erind village in the district of Gjirokastra, in Albania. Very similar to P. tymphii Willemse, 1972, and known in the region of Epirus in Greece, up to and slightly beyond the border in Albania, it nevertheless differs from the latter by obvious morphological characters such as the colour of its hind tibia, the shape of the genital plate of the female, the supra-anal plate, the furculae and several parts of the male phallic complex.

The lizard fauna of Togo, a country situated within a natural gap in the rainforest zone of West Africa, is reviewed and updated. In this article, we summarize all available data on the distribution, ecology, and conservation status of the 43 lizard species of Togo. Species richness is uneven between vegetation zones. The submontane forest (ecological zone IV), despite being the smallest, houses the greatest number of species (n = 27), followed by dry forest (ecological zone II, n = 21). Currently none of the Togolese lizard species appears to be immediately threatened. However, several species are subjected to exploitation for the international pet trade and in-country use (bush-meat, fetish market), and could become threatened in the next decades. The intensity of this trade should be carefully monitored in the years to come.
